Clinical Rationale for Extraneal
Unmet clinical need
Limitations of fluid management in PD
Limitations of current osmotic agents
Necessity of the long dwell
Kinetics of peritoneal ultrafiltration
Extraneal as a new osmotic agent
Kinetics matching clinical requirement
11
Unmet Clinical NeedLimitations of Current Fluid Management in PD
Symptomatic fluid retention occurs in 25% of all PD patients1. In these patients:
Lower extremity edema 98.6%
Pleural effusions 76.1%
Pulmonary congestion 80.3%
Similar clinical observations have been reported from Japan2, the Netherlands3 and Sweden4

Limitations of Fluid Management in PD Hampered by Inflexibility
Complexity of dietary counseling
Hampered by compliance issues
May complicate management
Constrained renal excretion1
Gradual decline to anuria
Diuretic resistance

Rationale for the long dwell in PD: Intersection of two imperatives
Toxin removal imperative:
Small solutes removal fluid flow dependent
Middle and large molecular weight toxins are time dependent
Continuously wet abdomen required for therapy success
Realistic therapy imperative
Logistic burden and compliance

Rationale for Extraneal
Fluid management in PD is constrained by the consequences of the underlying disease resulting in a necessary high reliance on peritoneal ultrafiltration.
With dextrose-based solutions a long dwell can compound the difficulties with fluid management
There is an unmet need in fluid management in PD
Extraneal is uniquely suited for successful ultrafiltration during the long dwell, and can contribute significantly to fluid management in these critically ill patients

Extraneal Efficacy Conclusions
Superior UF compared to 1.5% or 2.5% Dextrose and comparable to 4.25% Dextrose
Significantly reduced number of patients with negative net UF compared to both 1.5% and 2.5% Dextrose and comparable to 4.25% Dextrose
Significantly increased peritoneal clearance of urea and creatinine compared to 2.5% Dextrose

Each patient was followed until drop out or completion of 12 months.
Once a patient discontinued (early drop out or completer), he was observed for an additional 30 days to collect adverse events, including death.

Mortality information from all clinical studies was combined to better describe the experience for Extraneal.
There were 366 Extraneal patients in this integrated safety database.

Summary of Clinical Trial Results
EFFICACY
Increased Ultrafiltration
Reduced percentage of patients with negative net UF
Increased peritoneal creatinine and urea clearance
Potential benefit in preventing weight gain and edema, and improving quality of life
SAFETY
Safety profile comparable to current therapy
Rash most frequent related AE
Increases in alkaline phosphatase, decreases in sodium and chloride, with no known clinical relevance
80
ExtranealOverall Summary
Patients on PD have limited therapy options for fluid management
Extraneal provides patients and their physicians a new dialysis solution that expands these options by sustaining effective ultrafiltration during the long dwell
The enhanced efficacy of the new solution is coupled with a safety profile comparable to existing solutions
81
Proposed Indication
Extraneal is indicated for a single daily exchange for the long (8-16 hour) dwell during continuous ambulatory peritoneal dialysis (CAPD) or automated peritoneal dialysis (APD) for the management of chronic renal failure.
